If I install my 2.5" autospring leveling kit and get an alignment, do I need to get it aligned again when i upgrade to bigger tires?

 

yes

 

No you don't, an alignment should stay the same regardless what you put on...I had to take my mudders off to get the truck on the rack and the aligned it with the stockers then put the mudders back on afterwards

 

I could see having to re-align if you're using different wheels with those tires. More offset could cause a loss of ride height and throw the toe setting off.

 

No.

 

Hmm this is interesting... I am going to be changing wheels as well... rockstars with 5" backspacing. As for the tires I'm getting 33x12.50 toyo m/ts. Can anyone back this up?

 

I changed to larger tires twice. Added new wheels once, and did not need an alignment. When I replaced front shocks, I needed an alignment. I think adding the spacers and having to drop the coil overs to do so will require an alignment, not the wheels and tires.

 

Wheels/tires will not cause you to need an alignment. Only something that would change the geometry of the front end. ie where the spindle/hub is in relation to everything else. Normally shocks will not require an alignment, however, with the new coilovers, you have to pull everything to do the shocks. You might get a change in the geometry, however, I would expect it to settle back before too long. If you change thing like ball joints, tie rod ends etc. Then get an alignment.

It all depends on how long it's been since you got the initial alignment after the leveling kit install. If it's been a long while I'd get another alignment when you add the larger tires, to keep them from wearing prematurely.

 

Changing the offset of the wheel will do just that. Small changes in offset, not so much. But assuming he's going to at least an 8.5" wheel, that 5" backspacing is going to move the wheel center line 1.5" outboard. It's bound to change the ride height with a longer lever compressing the spring. Might not be enough to require an alignment, but why waste new rubber on speculation.

 

Offset will not affect it. It is just a matter there on how far the wheel sticks out.

 

Wheel offset will affect an a-arm suspension design. It's a matter of statics and dynamics. You have to look at the a-arm, spindle and wheel as a lever that is applied against the spring. You get a longer lever by moving the wheel outboard and it will exert more force against the spring. Wheel offset will not affect a straight axle design. I saw this time and again with Ford's TTB suspension system and the impact wheel offset had with camber adjustment.

 

All I know is, my Roush 8 1/2s did not require an alignmenmt and I put about 25,000 on the 305/50/20s before installing new shocks. At 92,000 miles, I had my first alignment

 

i'd do it anyway
